I was relieved by my previous employer and was provided a releiving letter as well as the full and final settlement statement. However, my full and final amount was not paid to me for over 4 months. After repeatedly writing to them and asking for a response I received a response from the CEO stating that payment from certain csutomers were still not recovered and that my full and final settlement would be completed only on recovery of those dues. As a senior management employee those sales did happen during my tenure but reamained unpaid even after I was releived. Under the given circumstances what legal reourse do I have? How can the company ask me to recover dues after relieving me ?
